The Exploding Baggie Experiment
Get a real bang out of this fun Exploding Baggie Science Experiment that will have the kids wanting to perform again and again. This is an outside experiment that should only be performed outside and care should be used to not get to close to the experiment when the reaction is taking place.
When vinegar and baking soda come together, the acid and base react to create carbon dioxide gas. The gas needs room that the baggie cannot offer, so the gas fills the baggie until it reaches its capacity and eventually explodes.
The tissue and paper towel in this experiment create a temporary barrier between the two substances which gives you the time to close the baggie and either toss it or run. This is because the baking soda can’t react with the vinegar until the paper towel has become saturated enough to allow the two substances touch each other.
